Summary

Orthopedic surgeons demonstrate high accuracy in visually estimating angles, typically within 10 degrees. Their estimation consistency over time is also reliable, irrespective of experience level.

Area of Science:

  • Orthopedics
  • Medical Imaging
  • Surgical Skill Assessment

Background:

  • Visual estimation of angles is crucial in orthopedic procedures.
  • Previous research has not sufficiently evaluated the precision of angle estimation by orthopedic surgeons.

Purpose of the Study:

  • To assess the accuracy and consistency of visual angle estimation among practicing orthopedic surgeons.
  • To determine if experience influences the reliability of angle estimations.

Main Methods:

  • A series of angles were presented to practicing orthopedic surgeons for visual estimation.
  • The accuracy and consistency of these estimations were statistically analyzed.
  • Repeat measurements were taken after a 6-week interval to assess reliability.

Main Results:

  • Surgeons estimated angles within 10 degrees 93.1% of the time and within 5 degrees 64.6% of the time.
  • Repeatability showed estimations within 5 degrees 82.2% of the time and within 10 degrees 94.5% of the time.
  • No correlation was found between years of practice/training and estimation accuracy or reliability.

Conclusions:

  • Practicing orthopedic surgeons possess a reliable ability to visually estimate angles.
  • Surgical experience does not significantly impact the accuracy or consistency of angle estimation.
  • Acute angles (≤31 degrees) were consistently overestimated, indicating a potential area for improvement.
